This is the third set of speakers that have done this now and i am clueless to what is causing it/ why and its really bugging me!.

When they are plugged in they make a slight buzzing noise, when i move the cursor the noise gets louder, when i hover over an icon on the desktop the noise get a bit louder, when i hover over a link and it lights up the noise gets a bit louder.

Also when watching videos on youtube the noise is constant;y quite loud and you can hear it over the music.

On the front of the speaker is a headphone port. When i plug my headphones into it the noise plays though them. But when they are plugged directly into the back of the computer there is no noise at all.

The noise seems to react to activity on the monitor so i thought it might be causing the noise, i might be wrong.

If it makes any difference the speakers are plugged into the green headphone port on the back of the PC.And i have tried moving them further away from each other.It says ont he box the speaker are Magnetically Shielded.I have absolutely no idea what to do, if anyone has any ideas at all then let me know.

Thanks

Edit/ Read this somewhere, could this be it? sounds like it could be.

".they r picking up the interferance from the pc voltage that is running throught the system it doesnt take much power to listen to the litle stand alone speakers on your ipod ..but the pc is putting out more power than the iposd so it picks up the static rom the comp.parts"

My PC is under the desk and my speakers are on the desk.If this is the problem what could be a solution ?

Do you have onboard audio or a sound card? Sometimes onboard audio chips can cause static and interference in speakers and usually a dedicated sound card fixes it.

Can you plug in an ipod or similar device into the speakers and get the same interference? Keep the ipod as close to where you plug in the speakers on the computer. If you still get the interference, move the speaker cable away from the computer and see if it still happens.

Make sure the speaker audio and power cable aren't warped around any other power cables as well.

I do have onboard audio. I might get a soundcard and hope it solves the problem but if it doesnt it will be really annoying and a waste of money. I did read on a forum somewhere that a soundcard did not stop it. May get a cheap one to try though.

il try with a laptop/ ipod later and post the results.

When i was looking it up last night i found a site all bout the ground loop thing. I do partly understand it but there a so many things that could be causing it i dont know where to start!. :/

Im not sure if its anything i have done but the noise may have got VERY slightly quieter and i cannot hear it over the music. The onyl annoying this is i will ahev to turn the speakers off everytime i am not watching a video or listening to music because of the noise still being there and gettign louder when i do things like scroll down a page.

This is becoming less and less the case actually, poor circuitry / PCB's and no shielding mean that the sound is just as vulnerable still :/ people are trying to go digital with USB cards to try and bypass that issue though because the interference is obviously less outside of the case.

I had the same problem - loud noise-like intermittent interference when loading some bits of a web page, especially videos/flash. Then I discovered that it still happened when all outputs from the computer were muted but the speakers were turned on. In my case it turned out that re-routing the audio cable away from some mains and other cables solved the problem. Never had a problem with this before - my only change has been a network over the mains adaptor instead of wireless.

Modem is in a different room, no dvd or vcr devices near by, one radio 10 feet away with a cell phone.

What worked for me, as dumb as it sounds, was disabling my microphone through the windows recording devices window.

I don't have a microphone plugged in at all, but disabling it made my speakers go true silent, I thought I broke something at first, before I realized, my god, this is what silence is...

As a side note, I think it's wild that my soundcard's mic input is picking up all device activity. It's especially noticeable while playing video games, in that the complexity of the render determines the speed of the clicking noise, and as a result creates different humming sounds that are fairly audible over the regular game sounds.

Hello all,I was having a very similar problem, brand new LED monitor causing my speakers (old bookshelf CD/radio/ DUAL TAPE DECK) to do soft but regular and annoying interference noises. I solved it by untangling the audio cable going from sound system to onboard audio and routing it away from every other cable. Problem solved.
